To all whom it may concern Be it known that we, J OHN ROBERT SPEAK, of the-city of Winnipeg, in the Provinceof Manitoba, and JAMES MILTON BEAI'IIE, of the city of Calgary, in the Province of Alberta, 'tain new and useful Improvements in Building-Olips, of which the following is the specificatio The invention relates to improvements in building clips, particularly plaster board clips, and the principal object of the invention is to provide an inexpensively con structed metallic clip for insertion between the edges ofsheets of laster boards as used in wall construction, t e inserted cli-p being designed to reinforce the joints between the sheets and also to space the sheets one from the other a fixed distance. 7

With the above general object and other minor objects in view, which will become more apparent as the description proceeds, the invention consists essentially in a clip presenting a plurality of catches and fitted a spacer and arranged such that the catches catch the inserted edges 'of the plaster board and the spacer separates the caught edges a fixed distance apart. The

detailed construction of the clip is hereinvafter described, reference being had to the accompanying drawings in which 1iFigure 1 represents a face View of the ig. 2 represents a longitudinal sectional view through the clip, the section being taken in the plane denoted by the line X-X Fig. 1. 4

Fig. 3 represents a transverse sectional View through the clip, the section bein tliaken in the plane denoted by the line Y-Y i ig. 4 represents a perspective view of some of the wall. I

Fig. 5 represents an enlarged detailed 'hOIIZOIItal sectional view through a wall and showin in plan the clip as it. appears inserted in t e wall at the studding.

In the drawings like characters of reference "indicate corresponding parts in the several fi We wis here to explain that at the present in' wall construction plaster boards or heets are being utilized in'the ,wall to take the place of lathsor Canada, have ointly invented cer' the plaster board ata pair of tongues separated clips as applied in a plastered.

expanded metal and that where .such sheets are .used. they are simply nailed to the wall studding and the wall is completed by applying plaster directly over the exposed surface of the plaster boards. Experience has proven that it is advisable to space the sheets from one another in order to allow the surfacing plaste between the edges of the sheets and make a bond at the joint but it is found that a careless workman will not always do this so that the finished wall very quickly deteriorates.-

Further it has been found that after a time a finished wall shows cracks and that in the majority of cases these cracks appear in the plaster directly opposite the adjacent edges of the plaster board strips lying behind the plaster.

which, when inserted between the plaster boards, effects a set orpredetermined spacing of j the edges thereof and further strengthens or reinforces the plaster board by uniting them at the edges.

eferring now to the drawings; 1 represents. the clip which is formed from a sub- -The presentinvention provides a clipstantially rectangular strip of sheet metal 2 '.which is cut and pressed to provide an op--' positely disposed pair of catches 3 and 4 and an intervening spacer 5. In actual practice we find it convenient to form the clips and spacer by cuttirg the body of the plate as indicated at 6 and in a more or less semi-circular manner, the cutting forming by a cross piece 8. The tongues are then pressed back and bent into an L-shape to provide thecatches as best shown in Fig. 2. Here it will be observed that the spacer formed is really of a channel cross section having the sides thereof part of the catches.

The body' of the plate is perforated as indicated at 9 as is also the cross portion 8 thereof as indicated at 10 and nail holes 11 are also supplied for a closed.

In utilizing ard, which this appliance with plaster is supplied in sheets, the sheets of the plaster board, indicated by the referedges of the separate when applied to enter purpose later dis- I not only hold the plaster boards but that the and the otherwithin the catch 4. When this is done it willb'e apparent that the catches bodies of the catches provide a means for spacing the edges of the sheets a fixed distance apart. The space between the sheets is indicated by the reference numeral (see Fig. 4) and this space is determinedby the Width of the cross part 8 'of the clip. In Fig. 4 of the drawings it will be seen that we have shown one of the clips indlcated I at A in what might be termed a horizontal really only acts as a spacer.

position and at the vertical joint between the sheets and two of the clips indicated at B and C in what might be termed a vertical position in-one' of the horizontal joints between the sheets. Obviously by so placing the clips around the sheets all the sheets in the wall will be spaced a fixed distance apart both vertically and horizontally.

The clip A applied at the studding-can be nailed to the studding and in this location The clips B and C, which, it will be observed; appear be- I,

tween the studdings, not only act as spacers but as reinforcers between the unsupported parts of the sheetsbetween the: studdings.

After the plaster boards with inserted clips have been erected the wall, according to custom, is covered Wlth the outer coating of finishing plaster 16 which obviously covers over both the clips and the plaster boards. This finishing plaster bonds to the plaster board through the openings 9 of the clips and also can find its way through the openings 10 into the interior of the spacer and bonds with the plaster entering'the spaces between the edges of the plaster boards. -In this way it will be apparent that the clips shown at B and C w1ll be very firmly'bonded in the wall.

With these clips inserted in the wall there is no tendency for the finished wall to crack at the joints.

What we claim as our invention is 1. A wall board clip comprising a closed sided metallic plate presenting centrally thereof and atone side a pair of transversely ezgtending spaced and oppositely directed substantially L-shaped catches, the said catches being cut from the plate and the said plate being formed with comparatively large perforations in the. body part and with perforations passing transversely thereacross centrally between the bases ofthe catches.

2. A wall board clip comprising a closed sided' substantially rectangular metallic plate presenting centrally thereof and at one side a pair of transversely extending spaced and oppositely dii ectedsubstantially L-shaped catches, the said catches being cut from the plate and the said plate being formed with comparatively large perfora- JAMES MILTON BEA'ITIE.
